Hi Eric,

It's probably not going to work to try and get that exact same result - some complications are that sweep is only going to try to do miter joints and not stuff like this:




And also all your pieces here are not just rectangles like for instance here you've got like a trapezoid with a slanted top:



So that kind of stuff probably won't be particularly feasible for sweep to do all by itself.

However, I think that I can tune up how the mitering is done when you have the Twist = Flat option enabled, right now it is not working well with that combination but I think it will be possible to fix that up so that you would get a similar kind of result quickly like I think you were hoping.
